A method of processing data associated with mobility of a user equipment (UE) in a wireless network is described. A mobility management entity (MME) starts an activation procedure for a default bearer for a packet data network (PDN) connection associated with a local Internet protocol access (LIPA). If a base station rejects an establishment of the default bearer for the PDN connection associated with the LIPA due to a triggered handover, the MME transmits a PDN connection reject message including a cause value, and releasing a network resource allocated for the activation procedure.
